Background
In 2016, Shane Seizys entered into a binding plea agreement under Federal Rule of Criminal Procedure 11(c)(1)(C), pleading guilty to two counts of robbery and one count of brandishing a firearm during a crime of violence. In exchange, the government dismissed thirteen other counts — including eight robbery counts, four additional brandishing counts, and one felon-in-possession count. The agreed sentence was 348 months (29 years), consisting of two consecutive 132-month terms for robbery and an 84-month mandatory consecutive term for the brandishing conviction. The district court accepted the agreement and imposed that sentence.
In 2024, Seizys moved for a sentence reduction under 18 U.S.C. § 3582(c)(2), relying on a retroactive amendment to the U.S. Sentencing Guidelines — Amendment 821 — that lowered his criminal history category by reducing points assigned to offenders who committed their offense while under a criminal justice sentence. The district court denied the motion, and Seizys appealed to the Eighth Circuit.
The Court’s Holding
The Eighth Circuit affirmed the denial, holding that Seizys was ineligible for a sentence reduction under § 3582(c)(2) because his sentence was not “based on” a Guidelines sentencing range. Under § 3582(c)(2), a reduction is available only when the defendant’s sentence was based on a range subsequently lowered by the Sentencing Commission. Citing Hughes v. United States, 584 U.S. 675 (2018), the court explained that even sentences imposed under binding Rule 11(c)(1)(C) plea agreements can qualify — but only if the Guidelines range was “a relevant part of the analytical framework” the sentencing judge used.
Here, the court found the Guidelines range played no such role. The sentencing judge focused on what Seizys avoided by pleading guilty: the dismissed brandishing counts alone carried a mandatory additional 100 years under the then-applicable stacked § 924(c) sentencing scheme. The court explicitly acknowledged Seizys’s motive for accepting the stipulated sentence was to avoid a potential life sentence, not to secure a Guidelines-based result. The fact that the individual robbery sentences fell near the top of the applicable Guidelines range was, in the court’s view, incidental — the 348-month total was the product of the plea agreement, not a Guidelines calculation.
Key Takeaways
- A sentence imposed under a binding Rule 11(c)(1)(C) plea agreement is eligible for § 3582(c)(2) reduction only if the Guidelines range was actually part of the analytical framework used to set or approve the sentence — not merely because the sentence happened to fall near the Guidelines range.
- Where the record shows the sentencing court was driven by the concessions secured in the plea deal (here, dismissal of counts carrying a mandatory 100 additional years), the Guidelines range is not the “foundation” of the sentence and § 3582(c)(2) relief is unavailable.
- Proximity of individual components of a sentence to the applicable Guidelines range does not itself establish that the sentence was “based on” that range when the overall sentence was structured around avoiding a far greater statutory exposure.
- Eligibility for § 3582(c)(2) reduction is reviewed de novo by the Eighth Circuit.
Why It Matters
This decision reinforces a meaningful limit on post-sentencing relief under § 3582(c)(2) for defendants who accepted binding plea agreements. Defendants who negotiated away serious exposure — particularly under the pre-First Step Act stacked § 924(c) mandatory minimums — may find that the very benefit they secured (dismissal of catastrophic charges) now bars them from taking advantage of subsequent Guidelines reductions. The ruling illustrates that courts will look past numerical proximity to the Guidelines range and examine what actually drove the sentencing decision.
For defense practitioners, the case underscores the importance of building a record at sentencing that ties the agreed sentence to the Guidelines range — rather than solely to the charges dismissed — if the client may later seek a retroactive reduction. Conversely, for prosecutors, it confirms that substantial plea concessions can insulate a sentence from later modification even when Guidelines amendments would otherwise lower the applicable range.
